About the Samsung 32GB DDR4 RDIMM - DDR4 (M393A4K43DB3-CTD)
The Samsung 32GB DDR4 RDIMM (M393A4K43DB3-CTD) is purpose-built for Intel Xeon Scalable processors, delivering enterprise-grade memory performance across high-channel-count server architectures. This registered ECC module ensures data integrity in mission-critical environments where downtime is not an option, making it the standard choice for data center infrastructure teams and storage architects deploying multi-socket server configurations.
Operating at DDR4-2666 speed with CAS latency 19, the Samsung M393A4K43DB3-CTD provides balanced performance and stability for demanding workloads including virtualization, database management, and high-availability clusters. The quad-rank (4Rx4) organization maximizes memory density per channel while maintaining strict JEDEC compliance. Samsung's rigorous quality standards ensure compatibility across OEM platforms and enterprise deployments. With ECC protection and registered buffering, this module mitigates soft errors and reduces signal integrity issues in densely populated memory configurations. The 1.2V operating voltage adheres to power efficiency standards, and the 0–85°C temperature range supports both standard and thermally challenging data center environments. IT procurement teams rely on Samsung's track record for longevity and vendor support when standardizing on memory platforms at scale.
